NHTSA Complaint #11551681 — 2022 HYUNDAI SANTA FE

The issue with Hyundai 2.5 L turbocharged engines is getting a lot of exposure on-line. My story begins about a year ago with me complaining to the Hyundai service department about my 2022 Santa Fe Limited hesitating, lurching, and stalling (once) following acceleration from a complete stop, all without the Check Engine Light (CEL) illuminating (which the dealership said is needed to initiate troubleshooting). In addition, there is a common thread where dealerships are telling owners that it is "... probably bad gas." On 2 October 2023 the SUV started and was idling very rough, and as I drove off, the CEL illuminated (finally). After turning off the SUV for five minutes, it started fine with no CEL. My OBD-II code reader pulled three codes from the SUV that afternoon: P0300, P0301, and P0302 (Misfire - General, Misfire - Cylinder 1, and Misfire - Cylinder 2). The trouble codes should be sufficient for the service department to locate a problem, and to their credit I was placed in a loaner vehicle when I dropped the SUV off on 7 October 2023. So far (24 October), they have not identified a problem, even though there is a fuel injector Technical Service Bulletin (TSB) for multiple Hyundai vehicles (including my Make/Model/Year) that may or may not apply to my specific vehicle. Bottom line: The vehicle is unsafe to drive (as I told the service manager), has had this problem for approximately one year, and if the vehicle stalls when I am entering traffic it is not going to end well - not for me in a stalled vehicle and not for Hyundai after they had an opportunity to address the problem.
